I was set a task in University to make a website in short. Part of the requirement was to make each page link, if you are on that page not be clickable. There are a good few advantages to this, mainly, it being required in this case for usability. This can be done with CSS too, but the browser support is limited, as far as I know to Safari, Chrome and Firefox. I could ignore browser support, but this is kind of a key point also within the course that we must accommodate to older browsers.
